Screening Native Freshwater Molluscs for Establishing Aquatic Life Criteria
摘要
Abstract
A series of systematic studies on water quality criteria(WQC)has recently been conducted in China. Screening of test organisms is an important part for developing WQC. Molluscs are major components of test organisms for establishing aquatic life criteria. According to the WQC derivation guidelines of the US EPA, toxicity data of twelve typical native freshwater molluscs were collected and screened from the ECOTOX database and other published literatures. Three types of pollutants that are most toxic to molluscs were pesticides, heavy met-als and conventional pollutants. The species sensitivity distribution(SSD)of molluscs indicated that the cumulative probability of Semisul-cospira libertine to dinoseb was 21%, Lymnaea stagnalis to ammonia 8%and Corbicula manilensis to sodium nitrite 3%. These three mol-luscs were also sensitive to pesticide(dinoseb)and to conventional pollutants(ammonia and sodium nitrite). Thus they could be regarded as test organisms for the aquatic life criteria.关键词
